Windows Phone sales on the rise, T-Mobile says

At least one major U.S. carrier is reporting strong customer interest in Windows Phone devices, as T-Mobile says that the Nokia Lumia 710 has been one of its five most popular smartphones since its launch earlier this year. In all, T-Mobile says that “the mix of Windows Phone sales among our product portfolio has more than doubled in the past eight months” with the Lumia 710 and the HTC Radar 4G leading the charge. The carrier also reports that it has “seen a large number of first-time smartphone users select a Windows Phone as their device of choice with 55% of all upgrades to the Lumia 710 coming from a messaging or feature phone” and that “Lumia 710 users have some of the highest handset satisfaction scores among all of our customers.” All of this is probably cold comfort for Nokia, which has announced plans to lay off thousands of workers as part of a massive restructuring plan.
